Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual dip switch setting is used for component recognition, then the control system can identify standard and optional features, but the process becomes labor-intensive and prone to human error

Engineering Contradiction:
Improvecomponent recognition accuracyVSAvoidcalibration operation complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The component performs self-identification by transmitting its own identification data to the control system upon connection. The microprocessor automatically detects and calibrates the component without requiring manual dip switch configuration, making the system self-servicing and eliminating human error in component recognition.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical dip switch system with an electronic communication system. Instead of physically setting switches, the component communicates its identity and parameters electronically through a communication interface, substituting mechanical operation with electronic automation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If automated detection and calibration systems are implemented, then labor intensity and human error are reduced, but device complexity increases

Engineering Contradiction:
Improvecalibration process efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control system incorporates a universal communication interface and microprocessor that can handle multiple component types through a single standardized protocol. This multi-functional approach allows the system to automatically recognize and calibrate various components (load cells, batteries, motors) without requiring separate dedicated circuits for each component type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a communication interface as an intermediary between the component and the microprocessor. This intermediary layer handles the complex tasks of data transmission, identification, and parameter exchange, simplifying the overall system architecture while enabling automated detection and calibration functions.

Inventive Principle:
Principle #24Intermediary (Mediator)
